Update 9:34am: LAPD released the name of the man arrested for allegedly making threats against L.A. school children in a Facebook posting.

Kyle Bangayan, 24, of Pomona was taken into custody Sunday afternoon after police searched his parents' East Hollywood home and found nine guns, including handguns, rifles, and a shotgun.

Who those guns belong to and whether they were obtained legally is still under investigation.

LAPD Commander Andrew Smith said police are hyper-vigilant in the wake of Friday's shooting at Sandy Hook Elementary in Newtown, Conn. This particular threat he said, was somewhat vague, not referencing any one school.

"It basically referenced what happened in Connecticut and it basically indicated that he was thinking about doing that type of thing at a school or schools here in Los Angeles," Smith said. "We don't know if he was actually planning on carrying these out, we have to assume he was, that's why he's sitting in jail right now."
